17

Consider the following before installing the DSLAM:

z

Installation Site – Your installation site should be well ventilated, clean, 

and free of environmental extremes. 

z

Installation Options – The DSLAM may be: 
— Mounted with the included mounting brackets in a standard 19-inch 

(483 mm) or 23-inch (584 mm) rack (including both Bay Networks 

and Nortel 23-inch racks), or, with separately purchased mounting 

brackets, in a 21-inch (535 mm) ETSI rack. ETSI brackets are 

available. See 

As many 4900 Series DSLAMs may be mounted in a standard rack as 

there are 1.75-inch (44.45 mm) spaces in the rack, so long as 

adequate cooling is provided.

— Mounted on a wall.
— Set on a shelf or desktop. 

Up to eight 4900 Series DSLAMs may be stacked on a shelf or 

desktop. Different models can be mixed in a stack.

z

Power – The DSLAM operates from a –48 VDC power supply to allow 

for standard power connections available in a CO. For AC voltage 

environments, an external AC-to-DC power converter is required.
